a The" present invention? relates to an, ar-

rangement for weighing goods in a hanging position, and the invention is speciallyndapted to be used in, connection with liftingcranes, derricks and the like, whereby it is f possible to weigh thegoods, while'hangmg n the hoisting apparatus. 1

x The invention is substantially character- I ized by the: fact,.that a locking .me'mber is fastened to a hoisting-wire or to apart connected with the same, which locking member cooperates with a -supporting .member, susv I pendedloy a'scale-wire sothat the goods after acertain lifting and following lowering are P automatically transferred from the hOlStlIlg-.

iwire to-the'scale-wire. V

J Figure 2 shows the: arrangement for transferring the goods from the hoistingewire to the scale-wire, in vertical section.

are running, which: are led through the outer .runs of the tripartite block and from the end of which a supporting member 13 is suspended, cooperating with a locking 1 parts 15 and .-15-f, enclosing the hoist- 'ingwire ,'3- so that this one runs, freely, through the same. The upper part of the casing is furnished with hol't-holes16- for screwing together the two parts of the casing and-for fastening hooks (not shown) to be' I J suspended by the wires 11 and -1Q-.

I The lower part of the casing hears two shafts In the lower parts ofthese arms, which are forked (Figure 3), a lever -19 resp.,

-+19'fis pivotally mounted, which is at'the inner end formed with an upright semithe outer end the levers are formed with a knot; -21-fresp.' .21 supporting the lowerendof a rod -22- resp. ,22'-', which is loosely mounted in a slot on the back of the;aI'ms.- 18. resp. -18'. To the mid.-

dle part of the shafts-.17- and .-17- plate- 7 members resp 23 are fastened,

lying in socket inthe arms 18* resp.

#187. v To the ends of thelshafts 17-,:

and +1Y' cranks 24 resp. '24;.- are fastened .betweenwhich a spiral spring 25+- resp. -25 is stretched, which nor- 1 r mally owing to theposition of the cranks proportionate to, the center line .of the shafts -17 and. -17,- forces the plate-members and f23-fagainst the upper edgeof the rods ,22.: resp. #227 and thereby together so that the parts -.,1'9 resp.

23', are by, a link +26% resp. +26?- connected with a disc 27 resp. 27",

pivotally mounted on apin. +-28,;resp.

" il 5ei when the springs +25 and 25-'- arelying above the centerline of ,the shafts --17 and -17-,'as hereafter further explained, the surface of the platemembers 23J-Jand -23- will engage with an edge 29. resp. -29' in the socket of 1 Thelowerend; o thehoisting-wire in. a tubular part -.3,l tothe' lower end, of

fivliich thehoisting'hook 6 is fastened.

In theupper end ofthe tube 3l-, whose diameter is somewhat smaller than the nner diameter of; the ring-shaped casing forniediby the collars --20-e and 20-f-,

is fastened a conical locking member 14- with a -collar--33T turned downwards and inwards, intended to co-operate with the collars -.-20. and 20"-', as hereafter furva little above the locking member 14- is fastened a conical part e-34 intended to ther explained. To the h0isting-wire -3 I co-operate with the discs 27- and 27.

T he arrangement operates in the following manner:

Suppose that some goods are hanging in the hook 6 with the parts in the position shown in Figure l, the locking member lel will during the lifting touch the le vers 19- and -l9 and push the same from eachother, as they are permitted to swing somewhat about their taps in the arms l8 resp. 1S, which arms at the same time are swinging outwards about the shafts -l'T resp. -1T- and thus permitting the locking member 14 to pass. Then the ifting stopped and by influence of the springs and -25'-, which are pressing the plate-members 2El-- and :'2 downwards, the arms l and lS'- will be led back, and the parts will get the position shown in Figure 2.

If new the hoisting-wire -3- is lowered, the locking member laas well the goods will be suspended by the levers 19- and -19-, and as the hoisting wire runs freely through a central hole in the locking member -1 l and may be further lowered together with the ring loosely placed in the tube -31, the goods will in thisway be quite released from the hoisting-wire and now be carried by the scale wire -'7, by which the supporting member 18 is hang-- ing by means of the wires 11 and l2-. The pointer of the scale S will now indicate the weight of the goods weighed.

At the same time as the locking member ll with the goods is suspended by the levers 19 and -19, the latter will swing about the taps and displace the rods 22- resp. 22 upwards, with the result that the plate-members -23 resp. --23-, being in touch with the same and being fastened to the shafts s-l7- resp. 1T-, will turn the shafts so much that the springs 25 and -25 will be lying above the center line of the shafts. lVith the springs in this position, the plate-members -23 and --'23'- are kept with their upper surface pressed against the edges -2Q reap. 29 in the socket of the arms lS- resp. 18, whereby the said arms now try to move away from each other,

what is however prevented, because the collar "-3 on the locking member --14 clutches the collar 20 and 20- on the levers 19 resp. 19. At the same time as the plate-members -23- and 23 swing upwards, the discs 27-- and -2'l"-, connected with the plate-members by the linlrs -i6 resp. -26-, will swing somewhat against the hoisting wire 3-. ll hen after the weighing has taken place, the goods shall again be transferred to the hoisting-wire, this one is hauled till the look ing member 14swith the collar 33-- has got clear of the collar 20-- and 20' on the levers -19- resp. 19--. On account of the position of the springs -25-- and 25 above the center lines of the shafts l7 and -l7, the arms -l8-- and -1S' will now swing outwards and permit the locking member --14 to pass. it the same time as the arms are swinging outwards, the discs -QT and -2'7 will be further swung against the hoisting-wire *3 and take such a position, that the conical part -3lduring the downward movement of the hoisting-wire will touch the opposite edges of the discs. and force the same outwards with the result, that the shafts -l7 and l'7- swing back, so that the springs -E25- and -25- are again coming below the center line of the shafts, whereby the effect of the springs will now be such, that the arms l8. and 18 are again moving into their starting position with the collars -20 and 20 in touch against each other and with the locking member l lhanging below the same.

The performance of the invention shown in the drawing is only stated as an example,

alterations may be made by the same without departing from the scope of the inven tion.

hat I claim is:

1. An arrangement for weighing goods in a hanging position including in combination, a supporting member embodying spring pressed grippers, a scale wire for suspending the grippers, a hoisting wire and a looking member in operable connection with'the hoisting wire for cooperating with the spring pressed grippers in such manner that after a cer'ain lifting movement by the hoisting wire the load is released so that the locking member will settle upon the grippers to effect weighing of the load and after the load is weighed the locking member is raised in order to be disengaged from the grippers while the latter automatically spring open to allow the hoisting wire to again take the load.

2. An arrangement for weighing goods in a hanging position including in combination,

supporting member, a scale wire for supporting the suspending lever the supporting member including arms pivotally mounted therein, springs for pressing the arms toward each other, collars at the lower ends of the arms, a hoisting wire movable through the supporting member, and aconical locking mem er carried with the hoisting wire and which during the lifting movement is forced between the arms and during the following lowering movement is suspended from the collars. r

3. An arrangement for weighing goods in a hanging position as claimed in claim 2, wherein shafts are provided for swingably suspending the arms, cranks on saidshafts to which the springs are connected so as to normally keep the arms pushed together, and

are automatically transferred to such a posibring tion that whenthe goods are again released from the arms,- the arms will again swing outwards and permit the locking member to pass freely. e
